Crescendo

8-Channel Microphone Preamplifier
in 120V-Technology

The Crescendo is the first microphone preamplifier that works with an internal operating voltage of 120V and breaks new ground.

The Undistortable

Imagine a microphone preamplifier with such a wide dynamic range and high overload resistance that the entire dynamic range of the microphone can be recorded without any limitations.

Imagine that the preamplification electronics themselves have no effect on the sound and you rediscover the sound of your microphones. With absolute signal fidelity and clarity. 

"With the Crescendo, I immediately have the feeling that I'm getting a whole new, unprecedented reproduction quality from all my microphones."

VU -10

In the Crescendo, high gains can be used to optimally drive subsequent AD converters. Should the VU meter therefore deflect too far, you can reduce the displayed level by 10 dB.

48 V

The phantom power required for the use of condenser microphones is activated with the 48V switch.

Ø

Turn the polarity of a microphone signal 180° by activating the polarity reversal switch.

Pad

For loud input signals (including line signals) the input sensitivity can be reduced by 20 dB.

Mic Gain

The gain is adjusted by a 12-step switch. The pre-amplification ranges from +18 dB to +70 dB.

"Even with the first test tones with the microphone connected, you notice that this 120 volt thing is not an empty promise. The dynamic range of the system is really impressive."

Inputs 1 – 8

The input differential amplifiers are constructed with pairs of transistors, each of which is combined in a housing. Precise matching of the transistors and thermal coupling ensure high common-mode rejection and extremely low THD values.

The choice of transistors and resistors has a decisive influence on the sound. In countless listening sessions the optimal components for Crescendo were selected – the effort was worth it!

Outputs 1 – 8

Our 120V SUPRA operational amplifiers work as current amplifiers, which also offer pure class A operation with over 6mA quiescent current. We largely dispense with coupling capacitors in order to avoid their sonic disadvantages (diffuse, sloping, loss of dynamics). In order to eliminate DC voltage components nevertheless, active servo circuits are used.

Alternate DB25 Output

For fast cabling to multi-channel converters, Crescendo offers DB25 connection.

“Good enough’ is rarely good enough for SPL, as this thoroughly over-engineered preamp testifies!”

The 120V Technology

What exactly is that?

And what does it do?

Good questions need good answers. And that’s what the 120V video gives you.

VOLTAiR is that good

In the lab, we pitted Phonitor xe against the best audio measurement system and found that Audio Precision could not measure VOLTAiR technology.
